Title: Digital camera
Inventor: KUBO HIROAKI
IPC: G03B7/099
Filed: 1999-05-07
Abstract: PROBLEM TO BE SOLVED: To enhance accuracy of dimmer by making a field angle of an image pickup sensor in matching with that of a dimmer sensor in a digital camera and to conduct dimmer control at the same time when main photographing is conducted. SOLUTION: A plurality of optical sensors 11-14 as luminous quantity measurement means 10 are placed at different positions in a space 8 between an optical unit 20 and an image pickup sensor 30 at the outside of an optical path of a direct light 9 made incident from a photographing object via the optical unit 20. A plurality of the optical sensors 11-14 can detect lightness of a photographing face 30a of the image pickup sensor 30 even during photoelectric conversion by the image pickup sensor 30. Thus, a dimmer control section 50 applies dimmer control at the same time when main photographing is conducted by conducting dimmer control of a flash light on the basis of the luminous quantity detected by a plurality of the optical sensors 11-14 in the case of photographing.

Title: Welding method of base pin for circular fluorescent lamp and lead wire
Inventor: IKEUCHI YOUICHI
IPC: H01J9/36
Filed: 1983-07-12
Abstract: PURPOSE:To improve the efficiency and to enable mass-production by inserting a lead wire through a base pin then performing the cutting and bending of about 90 deg. in the vicinity of the tip of base pin through single process thereby enabling good arc welding continuously. CONSTITUTION:A lead wire 2 is inserted through a base pin 5. Then a portion of lead wire 2 projecting from the tip of base pin 5 is cut by a cutter and bent immediately. Then the bent tip section 2' of lead wire 2 is welded by electrodes 7, 8 to the tip of base pin 5. It is bent about 90 deg. inwardly in order to provide accuracy to arc welding. Since single process is required from insertion of lead wire until welding, the workability is improved, mass-production is realized resulting in good welding.

Title: Glass passivation type semiconductor element
Inventor: KAWAKAMI AKIRA
IPC: H01L29/74
Filed: 1979-10-01
Abstract: PURPOSE:To improve tension resisting characteristics and reliability by a method wherein a glass passivation is performed in such way that the terminal of a P-N junction is exposed to the bottom region of a mesa groove which is formed shallower than the P-N junction. CONSTITUTION:On a silicon semiconductor wafer 105, on which a PNPN four-layer thyristor structure is formed by a prescribed diffusing process, a mesa groove 106 which is shallower than P-N junctions J1 and J2 is formed, the above junctions are made so that their terminals are located at the bottom of the mesa groove and a glass passivation film 107 is formed using a doctor blade method. Hereby, as a spacing between mesa grooves becomes wider, no wafer breaks during the process of manufacture and since the thickness of the film 107 is relatively uniform, the glass is hard to break, and a reliable mesa type element with an excellent tension resisting characterictic can be manufactured with an easy process of manufacture.

Title: Method for casting sand mold for cylinder block in multicylinder engine
Inventor: YAMASHITA KENJI
IPC: B22C9/24
Filed: 1980-09-12
Abstract: PURPOSE: To facilitate removal of core grids and cores from cast holes after casting and decrease bore pitches by burying reinforcing core grids into the cast holes connecting jacket cores to the short sides of outside walls.  
     CONSTITUTION: A pair of cast holes 12, 13 are formed in a way as to be continuous to the longitudinal parts existing on the right and left of a sand mold core 11 in one short side part of the outside wall of a cylinder block 4. A cast hole 13 is formed also at the center in the short side part of the other outside wall. Reinforcing core grid bars 14, 14 are buried in the longitudinal part of the core 11 by being penetrated at one end through the holes 12, 12. Hence, the deformation by casting pressure is obviated, and after the casting, the bars 14 are removed outward from the core 11 through the holes 12. Then, the core 11 collapses from the holes 12, 13, thus making the discharging of the molding sand easy.

Title: Manufacturing method of shadow mask for color television braun tube
Inventor: TSUDA TAKESHI
IPC: B21B1/22
Filed: 1978-10-18
Abstract: PURPOSE: To perform pressing while maintaining the annealing temperature of shadow mask low, by performing cold rolling on low carbon steel with specific pressure rate then performing the annealing with specific temperature on said steel band.  
     CONSTITUTION: Cold rolling is performed on low carbon steel with pressure rate of 10W35% to produce steel plate having depth thinner than 0.2mm, then said steel plate is photo-etched and annealed with temperature of 520W750°C thereafter passed through leveller board and pressed to obtain a shadow mask. Since the Braun tube manufacturer can anneal the shadow mask material with temperature lower than conventional annealing temperature of 750W900°C while the pressing can be performed even if the levelling times after annealing is lower than conventional one, the work efficiency is improved and the defective product is reduced.

Title: Original detecting sensor
Inventor: BABA NOBUYUKI
IPC: G03B27/62
Filed: 1997-05-01
Abstract: PROBLEM TO BE SOLVED: To improve original detecting accuracy without increasing a cost and to reduce the number of parts so that the cost is reduced by using a point light source LED having a fine light emitting area as a light emitting source. SOLUTION: When the LED having the small light emitting area is used as the light source 11, the beam of 15 mmϕ can be obtained in the case of the light emitting area of <=0.1 mm, for example. Thus, when the LED 11 having the small light emitting area is used for an original detecting sensor, the diameter of the emitted light beam becomes small, so that the diameter of the light beam on an original surface becomes small and the original detecting accuracy is improved. Besides, the diameter of a hole on the central part of a mirror 13 provided to make this light beam pass through is made small because of the small diameter of the emitted light beam, so that an area for a mirror part becomes large even though the mirror 13 having the same size is used; therefore, reflected light from an original is efficiently taken in a PD 5.

Title: Semiconductor surface light emitting element
Inventor: MATSUOKA TAKASHI
IPC: H01S5/00
Filed: 1989-05-22
Abstract: PURPOSE:To efficiently output a light by providing a Schottky type electrode on the side opposite to the face of an electrode having a light outputting window on its light emitting side. CONSTITUTION:An electrode 9 on the side (rear edge face) opposite to the emitting end is formed to be of a Schottky type. Since the electrode material of the Schottky type electrode 9 is not diffused in semiconductor, a boundary between the electrode metal and the semiconductor can be kept flat. Accordingly, the light propagated to the rear edge face is not absorbed to the rear edge face, and not reflected at random but reflected. That is, the decrease of Q of a resonator is prevented at the rear edge face. Thus, the light generated in an active layer 6 can be output without loss at the rear edge face.
